[Technical Field]
[0001] The present disclosure relates to a display device.
[Background Art]
[0002] Digital signage is a communication tool which may be used for marketing, advertising
or training by an advertiser and which may induce customer experiences, and is a digital
image device which provides advertising content intended by an advertiser in addition
to broadcasting content at a public place, such as an airport, hotel or hospital.
Digital signage has a processor and memory embedded therein, and may be used in department
stores, subways and bus stops for various usages, such as for public relations, customer
services and guidance media because it can be freely moved and can clearly represent
various types of content. Furthermore, only advertising content is not necessarily
provided, but various types of content having other purposes in addition to advertising
can be provided through digital signage.
[0003] In general, a plurality of LEDs is used in digital signage. The LED substitutes a
conventional fluorescent lamp and incandescent lamp because it has long lifespan and
high emission efficiency. Furthermore, the LED has been in the spotlight as a lighting
device because it has a small size compared to a conventional light source.

[0034] Referring to FIG. 1, the display device 100 may be attached to an attachment surface
250. The attachment surface 250 may be a transparent material. For example, the attachment
surface 250 may be a glass window. The display device 100 may be a transparent material.
For example, the display device 100 may include a transparent resin layer. Although
the display device 100 is attached to the attachment surface 250, the display device
100 and the attachment surface 250 can transmit light.
[0035] The display device 100 may display a screen. The display device 100 may forward emit
light. Alternatively, the display device 100 may emit light in the +z axis direction.
Light emitted from the display device 100 may pass through the attachment surface
250 and forward travel. Alternatively, light emitted from the display device 100 may
pass through the attachment surface 250 and travel in the +z axis direction.
[0036] Referring to FIG. 2, attachment surfaces 250A, 250B, 250C, and 250D may be fixed
to a frame 270. The plurality of attachment surfaces 250A, 250B, 250C, and 250D may
be fixed to the frame 270. A plurality of display devices may be attached to the attachment
surfaces 250A, 250B, 250C, and 250D, respectively. The plurality of display devices
may display a screen while operating in conjunction with each other. For example,
the plurality of display devices may divide a single screen and display the divided
screens. Each of the display devices may display a part of the single screen.
[0037] Referring to FIG. 3, the display device 100 may have a rectangular shape. A plurality
of light source assemblies 140 may be arranged in the display device 100. Connectors
150A, 150B, 150C, and 150D may be mounted along the circumference of the display device
100. That is, the connectors 150A, 150B, 150C, and 150D may be arranged on the four
sides of the display device 100. The connectors 150A, 150B, 150C, and 150D may surround
the plurality of light source assemblies 140.
[0038] The plurality of light source assemblies 140 may be electrically connected to the
display device 100. The connectors 150A, 150B, 150C, and 150D may be electrically
connected to the display device 100. The connectors 150A, 150B, 150C, and 150D may
be connected to the plurality of light source assemblies 140 through the display device
100. The connectors 150A, 150B, 150C, and 150D may transmit, to the light source assemblies
140, power supplied from a power source device. Furthermore, the light source assemblies
140 may receive a control signal, transmitted by a control device, through the connectors
150A, 150B, 150C, and 150D.
[0039] In the display device 100, an area in which the plurality of light source assemblies
140 is mounted may be called a display area F. In the display device 100, an area
in which the connectors 150A, 150B, 150C, and 150D are mounted may be called a bezel
area G. The connectors 150A, 150B, 150C, and 150D may be arranged on the four sides
of the display device 100 in order to smoothly transmit power and a control signal
to the plurality of light source assemblies 140. The ratio of the bezel area G may
be increased and the ratio of the display area F may be reduced because the connectors
150A, 150B, 150C, and 150D are arranged on the four sides of the display device 100.
[0040] Referring to FIG. 4, the connectors 150A and 150C may be arranged along one side
of the display device 100 and the other side parallel to the one side. Alternatively,
the connectors 150A and 150C may include a left connector 150A and a right connector
150C. The left connector 150A and the right connector 150C may be arranged to face
each other.
[0041] The plurality of light source assemblies 140 may be positioned between the left connector
150A and the right connector 150C. The display area F may be positioned between the
left connector 150A and the right connector 150C. Alternatively, the display area
F may be positioned between the bezel areas G.
[0042] Compared to the case of FIG. 3, the ratio of the bezel area G can be reduced and
the ratio of the display area F can be increased. Accordingly, it may be advantageous
to display a large screen compared to the area of the display device 100.
[0043] Referring to FIG. 5, the connector 150A may be arranged along one side of the display
device 100. The light source assemblies 140 may be arranged in an area in which the
connector 150A is not positioned. The connector 150A positioned on one side of the
display device 100 may supply power to all of the light source assemblies 140. Furthermore,
the connector 150A positioned on one side of the display device 100 may transmit a
control signal to all of the light source assemblies 140.
[0044] Compared to the cases of FIGS. 3 and 4, the ratio of the bezel area G can be reduced,
and the ratio of the display area F can be increased. Accordingly, it may be advantageous
to display a large screen compared to the area of the display device 100.
[0045] However, in order to supply power and transmit a control signal to the light source
assemblies 140 through the relatively reduced connector 150A, an efficient structure
of the connector 150A or an efficient wiring structure of the display device 100 may
be necessary.
[0046] Referring to FIG. 6, the display device 100 may include a base 110. The base 110
may be referred to as a substrate. Alternatively, the base 110 may be referred to
as a plate. The base 110 may be a transparent material. Alternatively, the base 110
may have light transparency. The thickness of the base 110 may be very thin. For example,
the thickness of the base 110 may be 250 µm, for example.
[0047] The base 110 may have an insulating property. Power supplied to the display device
100 may be blocked without passing through the base 110.
[0048] In a process of producing the display device 100, heat may be applied to the base
110. For example, the base 110 may include a polyethylene terephthalate (PET) material.
If the thickness of the base 110 is sufficiently thick, the base 110 may not be thermally
deformed although heat of 200° or more is applied to the base 110 in a process of
producing the display device 100.
[0049] Referring to FIG. 7, an electrode layer 120 may be formed on the base 110. The electrode

for transmitting power supplied from a power source device. Furthermore, the electrode
layer 120 may function as a passage for transmitting a control signal transmitted
by the control device.
[0050] The electrode layer 120 may be coated on the base 110. Furthermore, the electrode
layer 120 may be coated on the base 110 in a very thin thickness. The electrode layer
120 may have light transparency due to a thin thickness. Accordingly, although the
electrode layer 120 is coated on the base 110, the display device 100 can have light
transparency.
[0051] The electrode layer 120 may include a metal nanowire. For example, the electrode
layer 120 may include an Ag nanowire. The Ag nanowire has high conductivity and may
have excellent light transparency.
[0052] Referring to FIG. 8, the electrode layer 120 may form a pattern. The pattern of the
electrode layer 120 may function as a wiring structure.
[0053] The pattern of the electrode layer 120 may be formed through an additional process
after the electrode layer 120 is coated on the base 110. For example, the pattern
of the electrode layer 120 may be formed by radiating a laser to the electrode layer
120 coated on the base 110. Alternatively, the pattern of the electrode layer 120
may be formed by etching the electrode layer 120 coated on the base 110.
[0054] Referring to FIG. 9, the display device 100 may include the light source assembly
140. The light source assembly 140 may be mounted on the base 110. Furthermore, the

[0103] Referring to FIG. 15, the first connector 151 may be separated from the base 110
in the +z axis direction. Alternatively, the first connector 151 may be spaced apart
forward from the base 110.
[0104] The first connector 151 may be electrically connected to the positive electrode 122.
Specifically, the first connector 151 may be connected to the first positive electrode
122a to the fourth positive electrode 122d. The first positive electrode 122a to the

[0110] An electric current supplied from the positive electrode 122 of the power source
device may flow into the negative electrode 124 of the power source device through
the second connector 153.
[0111] The thickness, width or breadth of the electrode layer 120 formed on the base 110
may be formed very thinly. Accordingly, although the electrode layer 120 is formed
on the base 110, the display device 100 may have light transparency. Alternatively,
a reduction in the light transparency of the display device 100 attributable to the
electrode layer 120 can be minimized.
[0112] If the thickness, width or breadth of the electrode layer 120 is formed very thinly,
a cross-sectional area of the electrode layer 120 may be reduced, and electrical resistance
of the electrode layer 120 may be increased. Furthermore, if the area of the display
device 100 is increased, the length of the electrode layer 120 may be increased and
electrical resistance of the electrode layer 120 may be increased. If electrical resistance
of the electrode layer 120 is increased, power supplied from the power source device
may not be uniformly supplied to the light source assembly 140. Alternatively, if
electrical resistance of the electrode layer 120 is increased, a control signal transmitted
by the control device may not be transmitted to the light source assembly 140.
[0113] Accordingly, a node may be formed on the left side of the first column C1 so that
the electrode layer 120 can smoothly transmit power or a control signal to the light
source assembly 140. By forming the node on the left side of the first column C1,
the first positive electrode 122a to the fourth positive electrode 122d and the first
negative electrode 124a to the third negative electrode 124c can receive power or
a control signal through the node. The connector 150 may function as a node. The first
connector 151 may function as a node that connects the first positive electrode 122a
to the fourth positive electrode 122d. The second connector 153 may function as a
node that connects the first negative electrode 124a to the third negative electrode
124c. The upper connector 152a of the third connector 152 may function as a node that
connects the second control electrode 125b and the third control electrode 125c. The
lower connector 152b of the third connector 152 may function as a node that connects
the fourth control electrode 125d and the fifth control electrode 125e.
[0114] The connector 150 may be formed to have a greater thickness, width or breadth than
the electrode layer 120. Accordingly, the connector 150 can have lower electrical
resistance than the electrode layer 120, and can more smoothly transmit power or a
control signal compared to the electrode layer 120.
[0115] Referring to FIGS. 18 and 19, a first resin 180 may be coated on the base 110, the
electrode layer 120, the connector 150 and the light source assembly 140. For the
bonding of the first resin 180 and the electrode layer 120, a primer process may be
performed on the electrode layer 120. After the first resin 180 is coated on the base
110, the electrode layer 120, the connector 150 and the light source assembly 140,
a thermosetting or photopolymer process may be performed. The first resin 180 may
be formed into a first resin layer 181 through the thermosetting or photopolymer process.
[0116] The first resin layer 181 may surround the connector 150 or the light source assembly
140. Accordingly, the connector 150 or the light source assembly 140 may not be exposed
to the outside. The connector 150 or the light source assembly 140 can be protected
against an external impact through the first resin layer 181.
[0117] The first resin 180 may have a high viscosity characteristic. For example, the first
resin 180 may be an optical clear resin (OCR). The first resin 180 may function as
adhesives due to the high viscosity characteristic. For example, the first resin layer
181 may attach the display device 100 to the attachment surface 250.
[0118] Referring to FIGS. 20 to 22, a second resin 190 may be coated on the base 110, the
electrode layer 120, the connector 150 and the light source assembly 140. For the
bonding of the second resin 190 and the electrode layer 120, a primer process may
be performed on the electrode layer 120. After the second resin 190 is coated on the
base 110, the electrode layer 120, the connector 150 and the light source assembly
140, a thermosetting or photopolymer process may be performed. The second resin 190
may be formed into a second resin layer 191 through the thermosetting or photopolymer
process.
[0119] After the second resin layer 191 is formed, a first resin 180 may be coated on the
second resin layer 191. For the bonding of the first resin 180 and the second resin
layer 191, a primer process may be performed on the second resin layer 191. After
the first resin 180 is coated on the second resin layer 191, a thermosetting or photopolymer
process may be performed. The first resin 180 may be formed in a first resin layer
181 through the thermosetting or photopolymer process.
[0120] The second resin layer 191 may surround the connector 150 or the light source assembly
140. Accordingly, the connector 150 or the light source assembly 140 may not be exposed
to the outside. The connector 150 or the light source assembly 140 can be protected
against an external impact through the second resin layer 191 or the first resin layer
181.
[0121] The first resin 180 may have a high viscosity characteristic. For example, the first
resin 180 may be an optical clear resin (OCR). The first resin 180 may function as
adhesives due to the high viscosity characteristic. For example, the first resin 180
may attach the display device 100 to the attachment surface 250.
[0122] The second resin 190 may be an optical clear resin (OCR). The adhesion of the first
resin 180 may be greater than that of the second resin 190.
